  • Includes the RCAN port connector (3-pin, pin header) for developing and evaluating the software using the RCAN.
  • All of the SH7239 signals are connected to through-holes for common ring connectors to facilitate the timing analysis with peripherals that use measurement instruments.
  • SH7239 data bus, address bus and on-chip peripheral pins are all connected to through-holes for application headers to allow the user to develop expansion boards.
  • H-UDI connectors (38-pin and 14-pin) are provided to connect the Renesas E10A-USB emulator
